00:00:00 - Thanks to Joe, it's the return of the Elon Musk Happy Hour! This time, Musk wants to send loads of people to Mars, probably forever. In traditional Science... sort of fashion we ask: is this a thing? And maybe more importantly, would you go? (Also, Ryan says go read Seveneves.)

00:31:03 - Mars is pretty dry, so it'll be important to stay hydrated once there. Kelly staves off feeling sick with water and Tums but manages to sneak in a plug for The Expanse series of books. Joe confuses everyone with his Fungal Fruit Soda. And Ryan has a beer called Bomb! because of integrity or something.

00:55:54 - PaleoPOWs are a lot like future guests of the show, both are riddled with uncertainty. Things begin a bit somber with the death of Sharon Gray, a botanist killed while doing research in Ethiopia. The reasons surrounding her death are heartbreaking, but a GoFundMe campaign has been set up to help young women succeed in science in her memory. As a complete about face, Joe thanks Angie RK for her recent iTunes review and Kelly thanks Simon L. for throwing some cash our way. Finally, Ryan expounds upon Colin from San Diego's theory about yawning and ends up doing a fair bit of research on the topic. Strap in.
